Before I Go to Sleep (2014)

Storyline : Forty-year-old Christine Lucas wakes up in bed with a man she does not
know, in an unfamiliar house. The man explains that he is her husband,
Ben, and that she suffered brain damage from a car accident ten years
earlier. Christine wakes up every morning with no memory of her life
from her early twenties onwards. Christine receives treatment from Dr.
Nasch, a neurologist at a local hospital who provides her a camera to
record her thoughts and progress each day, and calls her every morning
to remind her to watch the video in the camera.
